When building a roof, carpenters put vertical boards every 2 feet along the horizontal baseline. The height of the boards, y, for the roof shown can be represented with the equation:

y = 0.4x,

where x is the horizontal distance from the nearest corner. How far from the corner is the board that is 4 feet tall?

Jude Hester · Answer 1

10 feet

Step-by-step explanation:

define variables:

y = height of the boards

x = distance to corner

we are trying to figure out what x is since we know the height of the board

4 = 0.4x

divide both sides by 0.4

10=x
